Hi,
I just wanted some clarification on understanding Article 230.40, Exception #5, as well as Article 230.71 of the NEC 2014.
Article 230.40, Exception #5, states, "One set of service-entrance conductors connected to the supply side of the normal service disconnecting means can supply standby power systems, fire pump equipment, and fire and sprinkler alarms [230.82(5)] as well as Solar PV systems [230.82(6)]".
I guess I should also mention the orignial article, Article 230.40 which states, "Each service drop, service lateral, or set of underground or overhead service conductors may only supply one set of service-entrance conductors".
Things that I'm thinking:
--How could service-entrance conductors supply power to a PV system, or any other standby power supply? Doesn't a standby power supply.... supply non-utility power?
--How is this considered an exception? It sounds pretty close to the parameters of the original article.
Thank you reading!
Kind Regards,
Andy
